as above,

ive heard they should only be left on for setting up purposes but... in the instuctions that come with the regulator it says "if you do not want to keep the pressure gauge on after setting up relive pressure then remove and replace bung",

so now im confused can it stay on there or not ive seen othe cossie's etc with them left on permanent

the gauge i have is a small liquid filled marshall 0-100psi that i bought from the same people who supplied aermotive regulator 13109,

cheers

 

also it says to use -6 with o rings?

does that mean normal male/male -6 with dowty seals on the reg side?

 

 

Read a topic on inline pressure gauges a while back, where it stated it shouldnt be left on the vehicle but it was actually ok to leave it permenantly installed.

Thats about all i can say really, ive seen enough cars with them permenantly installed i personally would of thought it would be ok, up to you though
